MACHINE FOR UPSETTING METAL BARS.

SPECIFICATION forming part of Letters Patent No. 394,011, dated December 4, 1888.

Application filed April 16, 1888. Serial No. 270,725. (No model.)

` Quebec, Canada, have invented a certain new and useful Machine for l'psetting lroluSteel,

or other Metals, of which the following is a specification.

The object of ille invention is to design a lllachine ill which iron, steel, or other lnetal may be upset. and sin'lultaneously forllled into any desired shape without ill any way injuring the nletal; and it consists, essentially, of a nlachine having a slowly-llloving ranl arranged to upset llletal by direct and steady pressure, rlailjlrocating rollers acting on the nletal and driven at a high rate ot' speed, lleillg operai ed ill connection with the slowlynlovillg raul for the purpose of keel'ling the llletal straight duringI the operation ot' upsetting, alld atthe sallle tinle'forln the said lnetal illto any desired shape, the whole being constructed alld operated substantially as hereillafter lllore particularly explaillel'l.

Figure il. is a perspective view of lny inlproved upsetting-nlachine, with a portion ot' one of the guide-bars brokell away. Fig. 2 is a cross-section of the special center rollers alld side dies llsed ill upsett illg and rolling` eye-bar heads. Fig. $3 is a plall of the saule rollers.

l-lefore referring to the specific parts of luy lnachine l nlay say that I do not clainl anything new ill all upsetting-machille llavillg a slowly-lllovillg ralll for the purpose of upsetting the nletal, as l aln aware that such lllas chines are now lnade; but in all nlachin es of this kind with which I anl li'alniliar the bar of lllletal being upset is distorted, and if of iron the libers are bent and separated by the spreading force caused bythe compressing force of ille raln.

In the adoption of; quickly-n1oving Vrollers arranged to operaie over the portion of the nletal being upset l aln enabled to keep the fibers of all .iron bar strz'llight, to keep a steel bar froln folding back on itself, and to increase the strellgth ot either lnetal by additional 'l working, whichthis rolling gives it,

ln ille llrawings, A is a heavy bed-plate, on

ll is a drivillgpulleycarried on a shaft suitcated, or ill any other suitable nlanner, to the shafts alld I), so that the said shafts shall revolve with ille d rivillg-pulley ll.

A hydraulic cylinder, E, is securely bolted to the bedplate A, and is preferably connected, to the head-block lA by the rods (l, which act as guide-rods for ille truck ll. The lower rollers, l, are suitably jourllaled ill the lower portion of ille truck ll, and the upper rollers, J, are journaled ill suitable boxes` K, held ill guides fornled on the upper portion of the truck ll. Each ot' the boxes l( is suitably Connected to a spindle, l), which spindles are all connected together, as indicated ill Fig. l, by gearillg operated by a hand-wheel, 3l, so that the rollers .Iv lnay be readily adjusted vertically nearer to or farther frolll the rollers l to suit the thickness of the nletal being aeted upoll.

The hydraulic cylinder 'E is ('onneetcd to any suitable hydraulic pu nlp, ille ezln st ruci ioll` of which is not necessary to be described ill this specification; but lprefer one which I have specially-designed for the purpose, alld intend describing it ill a separate application for a patent. This plllnp is operated by the shaft: C, which is connected to the crank-sha ft ot' the pulllp by the pitnlan N, as sllowll.

The truck Il derives a reciprocating lllotion from the shaftl), to which it is connected, as indicated, by the connectingwrods (l.

The erosshead P, connected to the plunger of the hydraulic cylinder E, is connected to the elld die, Q. lt follows, therefore, thatwhen the nlaehine is ill operation the truck ll, has a quick reciprocating lllot ion, while silllnltaneously ille cross-head l with its elld die, Q, is slowly nloved longitudinally toward the head-block F. The rollers I and .l will of course be lnade any shape which ii. is desired. and intended to form the nletal to be upset, and are located at such a point that they will travel backward alld forward over the surface ot' the nletal where it being upset.

In operation luy lnachine acts as follows: The bar R, which ill the drawings represents which all the parts of lnyn'lachine are carried. l the piece of nletal to be upset, is iirst heated IOO at the point to be acted upon, and is then inserted between the side dies, S, and is locked in position by the cams T. The machine is put into operation and the end die, Q, is brought slowly against the end of the bar R, and is pressed against it with a steady powerful force sufficient to upset or enlarge the cross-section of the bar, which naturally has a tendency to increase in thickness, Abut which is kept to a uniform thickness by the rapid reciprocating motion of the rollers I J; or, if the metal is to be formed into any other desired shape than that shown, the forms of the rollers and dies are changed, and by their action willY shape the end of the bar R into the desired form. The reciprocating action of the rollers on the bar R is very beneficial in working the metal while it is being upset, as it retains the fibrous character of the metal, if of iron, and works out all blow-holes, small cracks, &c., in steel, due to imperfect rolling in the process of its original manufacture.

I have shown my combined upset-ting and rolling machine, with the upsetting-plunger driven by hydraulic power and the roller-truck driven, as described, from the dri\f"ingpulley B. The upsetting -plunger might also be driven by steam or other power, and the truck by steam or other power direct. I therefore do not confine myself to any particular motor power. y

Vliat I claim as my invention isl. In an upsetting-machine, a slowly-moving die for longitudinally compressing the bar being upset, combined with quickly-moving rollers for vertically compressing said bar, and suitable side dies by which said bar is laterally formed or shaped, substantially as described'.

2. An end die arranged to act against the end of the bar being upset, and means for giving said die a slow but powerful longitudinalV movement, combined with rollers arranged to act on the portion of the bar being upset, means for giving said rollers a quick recipro eating movement, suitable side dies for forming or shaping the metal forced into them by the end die and rollers, and clamping devices constructed to grip the bar being acted on and sustain the quick reciprocating motion of the rollers, substantially as and for the purpose specified.

3. In an upsetting-machine, a slowly-mov ing die constructed to longitudinally compress the bar being acted upon, combined with quickly-moving rollers arranged to simultaneously laterally compress the bar and to pass over the surface of that portion of the bar being upset, substantially as and for the purpose specified.

4. An end die arranged to act against the end of the bar being upset, and means for giving said die a slowbut powerful longitudinal movement, combined with rollers arranged to act on the portion of the bar being upset, means for giving said rollers a quick reciprocating movement, and clamping devices construct-ed to grip the bar being acted uponv and to resist the longitudinalmovement of the end die and sustain the quick reciprocatingjmotion of the rollers, substantially as and for the purpose specified. Y

The guide-rods G, the cross-head P, supported on said guide-rods, andthe end die, Q, actuated by said cross-head, combined with the truck H, supported on said guide-rods, the rollers I J, and means for giving said truck a reciprocating movement to cause the said rollers to act on a portion of the bar being upset, substantially as and for the purpose specified.
